Surface Solder Redress Tool

Disclosed is
a device that will remove excess solder from the
surface of circuit boards. This tool is
unique in that it can remove
a relatively wide width of solder in one pass. There is no commercial
tool that can do this.

The figure
below illustrates the redress tool. It
consists of
a heat resistant handle to which is mounted a heater block. This
block contains a cartridge heater that conducts heat down to the
nozzle. When the nozzle is held against
a surface soldered pad, the
heat will melt the solder. A thin
rectangular slot in the nozzle is
internally connected to a solder trap with filter. The solder trap
has a vacuum hose connected to a finger-operated valve that when
depressed will deliver vacuum to the slot in the nozzle. This vacuum
will suck liquid solder into the solder trap. The end of the nozzle
has standoffs at each end to prevent the nozzle from contacting the
surface pads and damaging them as the nozzle is passed over the pads.
The standoffs also allow a thin layer of solder to remain on the
pads, to prepare them for future component attachment.
